##global methods

These are helper methods that are added to the global object, the main reason is that they can handle null values, where the normal prototypes are not able to detect that (in a controlled way)

existy value

confirms that a value exists (i.e. is not null or undefined)
```
global.existy = (value)->
  value?

global.not_Null = global.existy
```

is_Number

returns true if value is an number or not NaN

global.is_Number = (value)->
  (typeof value is 'number') and value.is_Number()

is_Null

returns true if value is null

global.is_Null = (value)->
  value is null

file_Exists file

Returns true if file exists

global.file_Exists = (file)->
  if not_Null(file)
    file.file_Exists()
  else
    false

¶

using target,callback

simulates a ‘using’ or ‘with’ language feaure where the this object (inside callback) is changed to value
```
global.using = (target,callback)->
  callback.apply(target)
```

truthly value

Returns true if value exists and is not false

global.truthly = (value)->
  value? and value != false

log message

Simple wrapper for console.log
```
global.log   = console.log
```
